Personal Time I don’t have very limited time to work on this and having to sand individual parts will be very time consuming. I need parts that fit together but I don’t want to spend time sanding a bunch of parts that break. I will have to balance making the part good enough to work…

3D printer availability. My frames are depended on the 3D printers. So far the 3D printer availability is not bad in the ITLL. Shipping time. Many of the cheap parts on eBay are shipped from China, this can take half a month. Coding skills. In order to display the graphics on the TFTs, I need…

Here is a link to my design review for reference: https://www.aesdes.org/2016/03/01/design-review-report-swing-bike/ Due to my unique situation, time and resource wise I actually don’t have a lot of constraints on my project. Since I have a number of places and connections for welding (friends, coworkers, being able to use welding equipment off campus, etc.) I have…

Creating a handheld fan is no easy task. Add to that, the fan bladeless and even more challenges pop up. For this post I am focusing on the top 5 design constraints from a manufacturing, usability, and aesthetics standpoint. Making the product printable. Without the resources for molding, and the complex shapes that this project…

There are some constraints in my project that I originally neglected. Machine shop availability. I went to fleming to reserve the mill machine and the schedule looks pretty busy. Time. I tried to begin the soldering this week. And the process took me much longer time than expected. Shipping time. The shipping time is delayed…

My project is on the surface fairly straightforward (in my mind at least), although there are definitely some hurdles that I will need to overcome in order to get this finished on time. Quantity of Keys: I have a lot of single string assemblies to make and tune, around 30-40 of them (depending on which…

After spending some more time on this project, some more constraints have arisen that I did not see in the beginning. My top five constraints are: The pitch – getting the diameter and lengths of the tubes right so that the chimes actually sound good.  There are some equations for this but it may take…

My top five constrains are: Integration of sensors,  motors and fabric how far it can be pretty and functional. Aesthetic – what is my genre? do I belong to one, is it fine if I don’t or should I start looking for one to identify with? We talked in class today about the fine line in human embodiment…

Going into the final project of the semester I am looking forward to seeing what I am able to accomplish. However, while trying to do so, there will be a number of constraints. The top five constraints I have are as follows: Electrical Components- I have nearly no experience in electronics besides my circuits class…

As I’ve been working on my design and shopping for parts I’ve identified some constraints to the project: Time Undoubtedly, the process of making prototypes and testing will take much more time than I expect. This is something I have taken into account and intend to be aware of throughout the project. Parts/Materials Since I…

Like any project there are significant design constraints that I will have to overcome to achieve my goals with the project and succeed and making something functional and aesthetically pleasing. 1.) Manufacturing: Since a lot of this is still new, the manufacturing will probably be a lot of trial and error and experimentation. I have…

These are the top 5 constraints that exist for my glass writing boards: Permission/requirements from Housing & Dining and/or Facilities Management I have been trying for several days now to set up a meeting with the hall director in my building. This is a necessary step in order to understand the requirements/constraints imposed by my…

As I continue to push forward with this project, I am made aware of the challenges that I am soon to face. The school year is quickly coming to a close and I am constrained by the limited time left for design, iterations, and assembly. I am aware that there will be issues with my…

The following list highlights the top five constraints associated with my project: Wood Frame for Hourglass– The framework around the glass form will need to be milled or CNC’ed.  Since the frame will have multiple sides, some critical thought needs to go into this process. Hour(glass)– It is necessary to find the right glass form…

Circuits and Electronics – I have very little experience with circuitry outside of the Mechanical engineering curriculum so this project will be a great learning experience for me.  I’ve talked to Dan a few times and he is happy to help me through this project. Programming – Another important area of this project in which…

I have started testing last week and am still in the process of determining which sand and liquid medium to use. I am doing these tests before I spend the time to build a frame. As anticipated, my constrains are very similar to the challenges I mentioned in the Design review. However, I am now…

My project has been progressing since the last update. I have made a more developed CAD model (just missing valves) and have already procured the majority of the raw materials. Luckily the aluminum was cheaper than I thought and I was able to get it fully spec’d locally which makes the guys in the machine…

The most critical constraints in creating my Fistcycle project are as follows: Creating a design that looks how I want but is also rideable. Designing a bicycle frame from scratch has been difficult. Extending or changing the shape of a tube or two from a current design is simple, but a larger deviation from the…

Over the last few days, I have started designing and ordering the dynamic parts for my project. The list below are the top action items, that I need to complete for the success of my final toy. Hydraulic System – The mechanics behind making the spider move are going to be tricky. My idea is to…

One constraint is time, though that is likely true of any project. There are only so many hours in the day and more obligations than comfortably fit. Another constraint is finding the right materials for the rail and wheels. I want the door to slide easily and quietly across the rail. While the door itself…

I think my top five constraints are: (1) Time    I am worried that things will go wrong and I will have to much to do and not enough time to do  it all. (2) Money   Good quality wheels and trucks are going to make my wallet really hungry. (3) Finding the proper wood…

Material Selection I have yet to decide whether 3D printing or another option is the way to go. If I go with the 3D printing route, then I would not have to worry about making things fit together. I would, however, need to consider how big of a piece I could actually print. I also…

As I’ve started ordering parts and designing my project, I’ve identified the following constraints that I’ll need to work within over the rest of the project: Time – time is ticking, and I’m very cognizant of my limited time resources as the semester winds down. I’m planning on spending several days over spring break working…

I’ve made good progress this week like getting the pre-amplifier working which I will detail in a future post.  Today I want to discuss the constraints I’m placing on the project with the intention of making it as close as possible to what I want. Amplifier circuit must allow for overdrive While, it is not…

The primary constraints and concerns of the frame development process are as follows: Machine shop time. Getting parts into the machine shop queue is now my number one priority. There are a lot of parts, and they all need to be produced and validated. Most have already been submitted. Carbon fiber. Because machine shop has…

First off the Wine Knife is taking shape quite well, however with all design this project has a few constraints which I will detail below. Having spent a fair amount of time this week on Solidworks I have identified the first major constraint, size. The artifact is quite small, measuring, hopefully, just 5.5 X .8…

Time. Everything of mine requires gluing, painting, drying, sewing… All of which use a lot of time. And we only have about 7 weeks left in the semester, so I need to be even more aggressive about my schedule. I expect getting the lace to be the correct size then attaching it to the frame…

Time – Of course, time is the biggest constraint. There are only 7 weeks left in the semester, and I have several other obligations, such as Senior Design and a job, that take up a lot of time. Therefore, to complete this project I will have to stick to my timeline, and adjust the project…

Here are the top 5 constraints for my proposed wind turbine design. Altitude.  These small wind turbines are not very effective and won’t produce significant electricity unless they are at least 20 ft off the ground.  This is due to the drag force the ground exerts on wind. Blades.  Wind turbines require incredibly precise blades…

After developing roughly 60% of the infinity mirror clock, these are the constraints I have run into that I need to overcome in order to achieve the desired aesthetic and initial impression. Rewiring the lights to run on a battery pack rather than 120V household electricity Also maximizing the battery life so that I am…

Below are the top 5 constraints for the LED arrow piece listed in no particular order. Cost: As a college student with no substantial income, the cost is a large constraint on this project. I would like to keep the cost below $100 if possible for the project. I plan to do this by taking the…

My top 5 constraints with building a carbon fiber expanding table are as follows: 1.) Money: Carbon fiber is expensive and I would love to build a full dining table, but for now with my limited budget, a small coffee table will have to do. 2.) Skill: I have experience laying out carbon fiber, but…

I spent a couple hours today tearing down my newly purchased bike to see exactly what I’m working with. Luckily the engine is sound and will only need some basic maintenance before riding season this summer. After some work and research I have summed up my 5 biggest constraints. Time: Time is the biggest factor…

Time: It almost doesn’t need to be said, but the primary driving constraint on this project is the time remaining to have an operational product demo at the design expo in April. Cost: As with any non-defense/government project, cost will play a huge role in the components that I select to use. I am currently in…

Cost – Although 3D printing and raw materials are fairly cheap, the strong Neodymium magnets required to levitate the motor rod are quite pricey in the quantities that this project calls for. Along with the cost of the magnets, the solar cells and magnet wire are also fairly pricey. Wood Working – I have never done wood working outside…

1.) Size: The size will limit what facilities I can use to 3D print my project. If it is too large I will be unable to 3D print it in the ITLL and perhaps Protogenics as well 2.) Mass: Since this product is meant for the kitchen, it should be fairly light weight. I hope to…

Building the “box” the map will sit in. I am still unsure whether I want the map to be horizontal, vertical, or at an angle, but am leaning toward an angle for design purposes. I haven’t worked much with power tools so I am sure this portion of my project will be a definite challenge…

2 plates with identical patterns (necessary for Moire effect) By definition, a Moire effect is a pattern that emerges from moving two identical patterns against each other. Perhaps there are unique results from using two different patterns, but the intrigue in this project is really the production of distinct geometric forms solely from rotating one…

My top five constraints in no particular order: Cost – I want to keep the project under $100 if I can due to my own budgetary constraints. This will also force me to be innovative in the way I implement some things if my cost starts to get too high. Light Diffusion – If the…

Implementing the Arduino is not too much of a challenge, but the hard part is making the project aesthetically pleasing with all the electronics sitting on top of the base. Maybe finding a way to hide the Arduino with a dome cover is an option. Chandelier must be in equilibrium, balancing perfectly while hanging from…

3D-printing only (DIY kit for Thingiverse) No fasteners (all parts must align or lock together without fasteners) Print Time (2-4 hours per prototype, so I can only cycle through a couple of iterations per day) Material properties (must make design considerations based on one type of filament – eg: a snapfit feature designed for PLA may not work for ABS due to…
